Results of numerical modeling of two-phase liquid / gas flow on the basis of a simplifield model of oil chamber

Abstract

Numerical simulation results of multiphase liquid/gas flow are presented. Calculation was preformed for simplified bearing chamber. Work was kept within the framework of developing the methods of multiphase flows modeling in oil chambers of gas-turbine engine. At present there is no the instrument of the analysis, allowing to simulate the oil flow in oil systems, and oil chambers of gas-turbine engine. The tightening requirements to mass, overall dimensions and performance of the engine need to reduce of the oil system sizes and amount of the oil, used for lubrication and cooling of bearing with increasing of their resource. At present, oil chamber design based on successful previous experience of the similar work, but performance of oil system is checked only in process of the engine test. This problems in this case lead to significant time and financial expense, so this instrument of analysis allow simultaneously increase the bearing resource, reduce mass and size of the oil system. The most rational model of multiphase flow was also chosen and analysis of the mesh size influence on steady calculation results was made.
